Struct TensorRegistry 

pub struct TensorRegistry { /* private fields */ }

Complete tensor specification: which function heads are tensors and what symmetries their slots have.

Implementations

impl TensorRegistry

pub fn new() -> Self

pub fn register(&mut self, name: Symbol, spec: SymmetrySpec)

Register a tensor with its slot symmetry spec.

pub fn set_index_group(&mut self, label: Symbol, group: u64)

Set the index group for a label (e.g. “mu” → 1 for spacetime, “i” → 2 for internal).

pub fn spec(&self, name: Symbol) -> Option<&SymmetrySpec>

Look up a tensor’s symmetry spec.

pub fn index_group(&self, label: Symbol) -> u64

Look up an index label’s group (0 = ungrouped/default).
